tert-Butyl 3-ethyl-3-hydroxyazetidine-1-carboxylate (2.3 g, 11.43 mmol) was dissolved in DCM (10 mL) and TFA (15 mL) was added. The reaction mixture was stirred at RT for 2.5 h and then the mixture was evaporated. Ethanol was added and the mixture was again evaporated to afford 3.0 g (100%) of 70A. 1H NMR (500 MHz, CDCl3): δ 0.96 (t, 3H), 1.81 (q, 2H), 3.94 (m, 4H).
